+Subject: [PATCH] arm64: dts: rockchip: add USB3 host to rock-5a
+
+Enable USB3 host controller for the Radxa ROCK 5 Model A. This adds
+USB3 for the lower USB3 port (the one closer to the PCB).
+
+The upper USB3 port uses the RK3588 USB TypeC host controller, which
+use a different PHY without upstream support.

+Subject: [PATCH] arm64: dts: rockchip: add (but disabled) SFC node for Radxa
+ ROCK 5A
+
+This commit adds SFC node for Radxa ROCK 5A.
+
+since sdhci and sfc on RK3588s share pins(i.e. exclusive), it cannot
+be enabled both nodes at the same time. so status = "okay" is omitted
+here.
+
+you may be able to enable sfc (and disable sdhci) by fdt overlay.
+
+SPI NOR flash chip may vary, so use safe(lowest) spi-max-frequency.

+Subject: [PATCH] arm64: dts: rockchip: lower mmc speed for Radxa Rock 5A
+
+The previously stated speed of sdr-104 in is too high for the hardware
+to reliably communicate with some fast SD cards.
+Rockchip boards have a common bug when operating uhs speed, which will
+hang the system during a soft reboot.
+
+To be on the safe side, lower the speed to workaround.
